“…The properties of Al/B 4 C nanocomposite were also superior when compared to Al/B 4 C micro-composite [15]. A signif-icant increase in elongation of 6061 MMC samples was achieved after adding Al 2 O 3 /SiC reinforcement nanoparticles [16].…”

Owing to its outstanding mechanical and thermal properties, graphene has shown enormous potentials as an improvement material for composites. This paper investigates the properties of graphene-reinforced 6061 aluminium alloy Metal Matrix Composites (MMCs) with varying weight percentages (5 and 10 wt.% graphene) of reinforcement. Energy Dispersive Spectroscopy (EDS) and Scanning Electron Microscope (SEM) studies of the MMC confirm the presence and distribution of graphene particles in the Al6061 matrix materials. Mechanical properties such as tensile strength, hardness, and impact strength of MMCs were studied and assessed. Tensile and impact strength of the MMC's increased from 25 to 60 % by the addition of 10 wt.% graphene in aluminium 6061 alloys. The percentage of elongation diminished with the addition of reinforcement in the matrix. The most significant improvement in hardness can be found in additional graphene particles. Wear-test had been performed using the pin-on-disc machine at 10 N load. It was observed that the tribological behaviour of the composite improved after the addition of graphene in Al6061.

“…Actually, the erosion and size reduction takes place during the mixing of hybrid reinforcements in the alloy melt. Pandiyarajan et al [54] have developed Al6061/ZrO 2 / C composites containing different reinforcement ratio of hybrid reinforcements using stir casting technique and the microstructure of the hybrid composites has been observed to be uniform. Figures 13(a) and (b) show the surface plots regarding variations in the mechanical properties of hybrid composites with respect to reinforcement percentage of ZrO 2 and C particles.…”

“…In an experimental study conducted by Pandiyarajan et al [54], addition of ZrO 2 in the Al/ZrO 2 /C composites results in increased rate of microcutting of the composites that is an indication of increased brittleness of the composites. Figures 15(a) and (b) show that the microcutting of the composites is increased with increase in content of ZrO 2 for same C content.…”

This article focuses on the mechanical and wear properties of the Al-based hybrid composites fabricated by stir casting route. A wide range of literature has been consulted in this regard and it has been revealed that processing conditions can be tailored to obtain homogeneous structure of the Al-composites. The addition of ceramic particles has been found to be essential to provide requisite strength and hardness to these composites. Also, use of agro/industrial waste materials such as fly ash, red mud and rice husk ash as a complementary reinforcement reduces the density of the hybrid composites without compromising the mechanical properties. The literature review also indicates that addition of soft reinforcements along with hard reinforcements reduces the brittleness of the hybrid composites. Moreover, the presence of solid lubricants like graphite significantly improves the wear resistance of these materials. It has been noticed that incorporation of solid lubricants also helps in the formation of a protective tribolayer at the interface thereby reducing the wear rate and plastic deformation of these composites. In overall, study concludes that Al-based hybrid composites have great promise to serve as a substitute to the ceramic reinforced composites and the unreinforced Al-alloys in various automotive applications requiring low cost, high strength-to-weight ratio and superior wear resistance.

“…Reinforcements like particulate alumina, manganese dioxide, silicon carbide, graphite, fly ash, etc can easily be incorporated in the melt using cheap and widely available stir casting method [3]. The various fabrication procedures for MMCs, which are generally produced using two major methods, namely, solid and liquid modes of fabrication [4]. It has been reported that the abrasive wear resistance of particle reinforced MMCs increases with the volume fraction of particles, under both high and low stress abrasive wear conditions [5].…”

The present study deals with investigations relating to dry sliding wear behaviour of the Al 6061 alloy, reinforced with MnO 2 particles in 3, 6, 9, and 12 wt.% in four steps in stir casting process. The tests were conducted at varying loads from 0 to 15 N, track radius of 30 mm and constant speed of 1000 rpm. Effect of normal load are discussed and the wear resistance of the composite increased on increasing the MnO 2 particles thus wear rate is significantly less for the composite compare to matrix material. Tribological results reveals that wear rate is directly related with the load. The results show that the tribological behaviour of metal matrix composites (MMCs). The results indicate that the wear resistance of the Al6061 reinforced material increased with increase in MnO 2 content, but decreases with increase in normal load.
